Thanks to the ingenious structural framework planning, only a few parts of the old structure had to be strengthened. This resulted not only in a very economical solution, but also appealed especially because of the barely recognisable intrusion in the old, listed basic structure of the building. The Jahrhunderthalle Bochum is the main venue for the international cultural festival „Ruhrtriennale“ since the completion of the reconstruction in 2003
MAIN VENUE FOR THE RUHRTRIENNALE
The former Gas Power Centre of the cast steel company „Bochumer Verein für Bergbau und Gußstahlfabrikation“, an industrial listed building from the year 1903, was reconstructed at the beginning of the millennium to a concert hall and extended by a large foyer and a cloakroom building. The historic construction could be sensitively toughened by means of continually cambered cables. The installation of a structural heating screed provided intelligent strengthening for the basement slabs. The new building construction of steel was abutted on an old external wall and suspended via the toughened cables on the existing construction.
The extension of this protected, sophisticated structure with almost fully utilised components required an extremely cautious distribution of the additional forces in the old structure.
